Explore the fourth dimension, from processes that occur in billions of years down to tiny slivers of a second.

Ryan Coffee, scientist at the Linac Coherent Light Source, explains in a video interview.

SLAC celebrates five days of ultrafast science.

The study at SLAC’s X-ray laser was a step toward understanding how DNA defends itself from breakage and potential mutations.

X-ray studies have produced surprising insights into the workings of a hormone receptor associated with blood pressure regulation that could be a target for new medicines related to cardiovascular conditions, neuropathic pain and tissue growth.

A research collaboration designed a new assembly-line system that rapidly replaces exposed samples and allows the team to study reactions in real-time.

Paleontologist Phil Manning describes the “Imaging Life on Earth” project at TEDxCharleston.

New X-ray methods have captured the highest resolution room-temperature images of photosystem II.

Scientists used SLAC's LCLS X-ray laser to make the first snapshots of a chemical interaction between two biomolecules. It changes the shape of millions of molecular switches almost instantaneously, like synchronized swimmers performing the same move.

The team determined the 3-D structure of a biomolecule by tagging it with selenium atoms and taking hundreds of thousands of images.

SLAC’s X-ray laser provides clues to engineering a new protein to kill mosquitos that carry dengue and Zika.

The discovery is one of the first steps towards mapping hues of fossilized species.
